The blizzard that hit the East Coast Sunday and Monday could still be felt in much of the country on Tuesday.

Perhaps the biggest invoncenience of the two-day snow storm, which is being called the "worst in four years," was the airport closings that left thousands of holiday travelers stranded.

The three major airports in New York canceled all flights Sunday night and are now working to fit in travelers by the end of the week.

"With all the cancellations and delays, it'll be two to three days before the airlines are at a regular schedule," said Thomas Bosco, general manager of New York's LaGuardia airport.

People stranded in New York airports slept on luggage carousels and cots Sunday night, while others slept on the floor.

Rail and bus service on the East Coast was also hit hard, and many holiday travelers spent their days after Christmas on train platforms or hubs.

The New York Times reports:

Some 4,000 flights had been canceled in the region, and even as airports began to reopen, the backlog was so great that officials said it might take days to catch up.

Tens of thousands of homes remained without power, their lines cut by high winds and toppling tree limbs. Utilities reported 60,000 customers without power in Massachusetts, 8,000 in New York City and Westchester County, 8,700 on Long Island and more than 8,000 in New Jersey.
